It depends a lot on what you are doing and your innate abilities and determination. Knuth has captured some thoughts about staying connected via email very eloquently so I will share them here - "Email is a wonderful thing for people whose role in life is to be on top of things. But not for me; my role is to be on the bottom of things. What I do takes long hours of studying and uninterruptible concentration. I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don't have time for such study.
